Abstract (en)
[origin: US2020232855A1] A method, apparatus, touch chip, and electronic device for determining a temperature status of a touch screen. The method for determining a temperature status of a touch screen includes: determining, based on a plurality of sampled characteristic values of each temperature monitoring node in each sampling period, a raw characteristic value of the temperature monitoring node in a the sampling period, the temperature monitoring being selected from a plurality of capacitance nodes in a touch array; and calculating, based on raw characteristic values of all temperature monitoring nodes in each sampling period, a raw characteristic statistic value in each sampling period, and determining the temperature status of the touch screen based on a raw characteristic statistic values in sampling periods.
